The FBI has confirmed the discovery of classified documents in the Washington, D.C., office of former national security adviser John Bolton following a raid last month. According to court filings, the seized records included materials marked as confidential, some referencing weapons of mass destruction, U.S. diplomatic activities at the United Nations, and government strategic communications efforts.

The case has intensified scrutiny of Bolton’s handling of sensitive national security information, reigniting debates over accountability for officials who possess classified material. The discovery also echoes prior controversies surrounding Bolton’s 2020 memoir, which contained classified details and led to a legal battle.

Bolton’s lawyer, Abbe Lowell, asserted that the documents seized by the FBI were not from his time in the Trump administration but originated from earlier roles, including work under the George W. Bush administration. Lowell claimed the materials had been previously reviewed and approved for use in Bolton’s book, stating they were “ordinary records” kept by a long-serving government official.

The FBI’s inventory listed documents labeled confidential and secret, though it did not specify whether any had been declassified. The case has drawn attention to broader questions about the enforcement of national security protocols and the political implications of investigating high-profile figures.

Bolton, who publicly clashed with former President Donald Trump over his memoir, faces ongoing legal and ethical challenges over his retention of classified information.
